Yes, as observed.  However I believe changing message-id, even it it
were consistently across all headers and in both directions, would be
erroneous, as these might be used in extra headers as well, as for
linking, archiving, etc.  One message shouldn’t see its message-id
change that way, whatever the protocol used to transmit it.
